“The Secrets We Keep” (**1/2 out of four) was a moody but muted melodrama set after WWII in which a woman (Noomi Rapace) is struggling to rebuild her life after the war; upon meeting her neighbor (Joel Kinnaman) she believes he is a former Nazi war criminal and she kidnaps him to interrogate and inflict back the pain and suffering she endured in the war. Rapace is first-rate as usual and story has historical intensity but it’s somehow never as powerful or compelling as it should have been. Very similar story was told prior in Roman Polanski’s 1994 “Death And The Maiden.”
